Morphological comparison of the feeding apparatus of three co-occurring species of ponyfishes (Leiognathidae)
摘要
Abstract
Ponyfishes of the family Leiognathidae frequently show overlapping distribution patterns in the Indo-Pacific and South China Sea. The mouth morphology of three species of ponyfishes which feed at different levels in the water column were compared. The species could be distinguished primarily by the mouth morphology. Gazza minuta (Bloch) feeds mainly on benthos
has the least protruding jaws;Secutor ruconius (Hamilton-Buchanan) feeds mainly on plankton
has the most protruding jaws;Leiognathus rivulatus (Temmink et Schlegel) has an intermediate degree of jaw protrusion. This study showed that closely related species with overlapping distributions frequently exhibit morphological
physiological or ecological differences related to the search for food
the intake of food or locomotion mode.
